MUFFLER FOR FIREARMS.

Specification of Letters Patent.. Patented Sept. 27, 1910.

Application led October 2, 1909.

Serial No. 520,735.

To all whom it may concern.

Be i known that I, ANDY C, SHIPLEY, a citizen of the United States, and a resident of Speedwell, in the county of Claiborne and State of Tennessee, have invented certain new and useful Improvements in Mufiers for Firearms, of which the following is a specification.

My invention relates to devices for preventing the noise incident to the discharge of a fire arm, and has for its object the provision of a chamber secured to the underside of the gun-barrel connected with the bore and provided with small openings at its forward end and with a lurality of disks adjacent to the forward end with unalined openings to break up the discharge before reaching the small openings.

My invention will be described in detail heremafter and illustrated in the accompanying drawings, in which- Figure 1 is a side View of a rifle showing my improved muflier in position thereon; Fig. 2, a longitudinal sectional ViewV of the muler; Fig. 3, a cross-section on the line 3 3 of Fig. 2; Fig. 4;, a cross-section on the line 4 4 of Fig. 2; and Figs. 5, and 6, detail views of the perforated members.

In the drawings similar reference characters indicate corresponding parts throughout the several views.

A indicates a rifle of my preferred construction and B the barrel.

As is well known the noise from the discharge of a re arm is occasioned by the expansion of the gas-of the charge at the muzzle of the arm, and my invention is designed to prevent all of the gas from escaping from the muzzle and consists in the puovision of an expansion chamber connected with the bore of the arm, which consists of the tubular casing -1,.being a plurality of lengths of tubing 2, secured together byV function of not onlyL ret-ardin the barrel when the casing is in posit-ion. The underside of the forwardmost tube 2 is'also provided with a wedge-shaped notch 8 to receive a block 9, having a Wedgeshaped base l0 to engage the notch,fsaid block being provided with an elongated socket 11, with holes 12 in its base connected With holes 13 cut transversely through the block, the casing being provided with an elongated slot 14 that alines with socket l1 when the block 9 is in position.

15 and 16 indicate disks secured vin the forwardmost tube 2, disk 15 being notched around its edge, as shown at 17, to provide openings for the passage of the gases of the discharge, while the disk 16 is formed with openings 18 for the same purpose, said openings being unalined and having the the escape of the gas but also break its orce so that when it reaches the block 9, through which it escapes, it passes out with a slight wheezing noise that is indistinguishable a short distance from the marksman.

In operation as soon as the projectile,

passes the opening 7 in the barrel the gas from theexplosion enters the casing 1 and expanding therein passes through the openings 17 and 18 in disks 15 and 16, through slot 14 into socket 11 and thence through holes 12 and 13 to the outer air, a small' firearm, a tubular casing secured thereto and communicating with the bore thereof intermediate of the breech and muzzle, a block removably secured near the end of the casin said block having a socket anda plurallity of transverse holes communicating with the socket, and the casing provide with a slot in alinement with the socket in the block, 'substantially as shown and described.
